PAPER BOTTLE.

To all whom it may concern:

Be it'known that I, Jnssn H. PERRAULT, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented certain new and useful Improvements in Paper Bottles, of which the following is a specification.

This invention relates to improvements in paper bottles, especially milk bottles.

The objects of the invention are to provide a milk bottle that can be made by rapidly wrapping layers of paper and conform y suitably slitting and folding-with an annular groove formed therein to receive the milk bottle cover.

A further object is to so dispose the paper that the crease for receiving the cap in the bottle will be formed lengthwise ofthe fibers of the paper and not transverse thereto, whereby the paper may be readily stretched without danger of breaking or unduly weakening the wall of the container.

Objects relating to details and economies of construction and operation will definitely ilppear from the detailed description to fol- I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure showing a preferred form of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which: 1

Figure I is an elevation view of a milk bottle embodying the features of my invention. Fig. H is a detail transverse sectional view taken on a line corresponding to line.

Specification of Letters Patent.

Patented May '3', 1918.

Application filed January 19, 1916.. Serial No. 78,003.

Fig. V is a detail view, on a reduced scale, of the blank with dotted lines indicatin the position. of the overlapping folds or p aits, and full lines showing the slitted part.

Fig. VI is a detail sectional view showing a modification of the neck with a reinforcement added and extending below the angular crease to receive the cap, the bottle neck being shown of a single ply.

"Fig. VII is a modification in which the improved neck is made separate and attached, and may be fitted to a paper bottle formed in any way, or to any bottle.

In the drawing similar numerals of reference refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Considering the numbered parts of the drawing, the bottle ismade up of a cylindricalpart 1 of one or more plies of material, preferably a sin le ply, the breast 2 of the bottle being iormed by suitable folds 3 formin creases 4, with the upper part slitted an compressed into a neck '5, the paper being slitted at 8 whereby the same can be overlapped, breaking joints and forming a double layer at the neck.

In theneck is formed the shoulder groove 7 by any suitable die means for receiving the cap .10. This is preferably the usual milk bottle cap. The top of the bottle is flared at 9. The groove 7 is angular, as indicated at 11 ('see Fig. IV), with its bottom face slightly-inclined inward so that when the cap is pressed to place, it will become engaged in the sharp shoulder, making a very strong joint that makes the milk bottle a safe container in whatever positionit may be placed.

It has been found that this crease can only be formed in the paper efiectively and safely if the fibers of the paper run transverse to the bottle and transverse to the neck and in the direction of thegroove. If it is attempted to form an abrupt crease crosswise of the fibers of the paper, the wall is very much weakened and the security of the package is very greatly impaired.

In Fig. VI, I show a supplemental reinforcing top portion 14 folded onto the upper edge of the milk bottle at 15, and if the fiber of the paper of this portion is disposed as I have indicated a. strong and eetive top will thus be produced, no matter in what direction the fibers of the paper forming the bottle or container 12 may be disposed, and the'same may be a plain paper neck of any design.

In Fig. vVII, I show a modification in which the top 13 is shown as a, separate part from the neck of the bottle 12 to which it is attached, and is simply formed independently to be inserted and glued or otherwise retained in the neck of the bottle.

From this description it will be clear that this structure can be greately'modified in its details without departing from my invention. I have shown modifications which make-the structure entirely practical for a great variety of conditions, but these are only prominent instances in which the invention may be utilized and are intended as examples to indicate that the invention is capable of being utilized in a great variety of ways. I desire to claim the specific forms which I have illustrated, and also desire to messes claim the invention broadly as pointed out in the appended claims.

Having thus described my invention what Let- . said groove.

2. A neck for a paper bottle, the fibers 0f the paper of which are disposed transverse to the neck, and a groove formed in the neck for receiving the cap of the bottle, as

specified.

In witness whereof, I have hereunto set nesses.
